  1. Issue Team Recommendationsfor Wood & CFS Mid-rise light-frame shear wall buildings New soft-story structures New hillside structures New open front structures Light-frame structures with masonry veneer

  2. Mid-rise Light-frame Shear Wall Buildings:Performance, Design, Detailing

  3. Mid-rise Light-frame Shear Wall Buildings:Performance, Design, Detailing • Issues: • Extended into mid-rise construction without adequate knowledge of seismic performance • Is adequate safety provided? • How do we design for performance? • What tools are needed for multi-story stacked shear wall analysis and design?

  4. New Soft-story Structures:Reconsider Irregularity Implications

  5. New Soft-story Structures:Reconsider Irregularity Implications • Issues: • Analysis and shake table testing consistently shows that light-frame construction exhibits extreme soft story behavior, regardless of design to avoid this behavior • Study is needed to consider what is achieved by current code limitations and practical ways to approach new building design

  6. New Soft-story Structures:Reconsider Irregularity Implications • Resources: • San Francisco CAPSS/ATC 71-1 • CUREE-Caltech Woodframe Project • NEESWood Project • UC Berkeley House Testing • Others?

  7. New Hillside StructuresDesign Recommendations

  8. New Hillside StructuresDesign Recommendations • Issues: • In the Northridge Earthquake, collapses occurred in light-frame hillside structures • A substantial portion of housing inventory is of hillside construction • Current code permits design of hazardous buildings

  9. New Hillside StructuresDesign Recommendations • Resources: • Northridge earthquake experience • City of Los Angeles ordinance • CUREE-Caltech woodframe project

  10. New Open-front Light-frame Structures:Design Recommendations

  11. New Open-front Light-frame Structures:Design Recommendations • Issue: • Current code permits construction of potentially hazardous buildings

  12. New Open-front Light-frame Structures:Design Recommendations • Resources: • CUREE-Caltech Woodframe Project • Analytical study by Jian Xu – WSU • TS7 work from 2003 Provisions

  13. New Light-frame Structures with Masonry Veneer: Design Recommendations • Issues: • Demands on light-frame structure from masonry veneer • Anchorage of veneer to structure • Resources: • NSF/NEES Project

  14. Issue Team Recommendationsfor Wood & CFS Mid-rise light-frame shear wall buildings New soft-story structures New hillside structures New open front structures Light-frame structures with masonry veneer
